Abstract
A method for eliminating hydrocarbon vapors generated in a fuel tank of a vehicle powertrain including at least one heat engine, by a canister adapted to absorb the vapors. The method includes detecting movements of the hydrocarbon vapors from the tank to the canister, increasing a counter value when the vapors move from the tank to the canister, and calculating a number of gas volumes passing through the canister when the heat engine is started so as to reduce the value of the counter by purging the gasoline vapors in a direction of the engine.
